Clutch Recommendations

[OED666]

I suppose the 63 Option 3 Plus XR6T clutches sold last year speak for themselves... By the looks of it, 2 had issues (1 was due to grease on the flywheel as posted earlier). Yet to get any firm details from STAINLESS on his clutch.

Also, another modified XR6T on 20psi, 453RWKW with an Option 3 Plus, with more power than the clutch is rated for, and its holding!! In the words of Basil Fawlty, "a satisfied customer, maybe we should have him stuffed!"

Runs 12.69 @ 127.7MPH. The time isn't great, but the MPH is quite impressive. The attached dyno sheet was shortly after the clutch went in, and then it got a few more things done to it.

Maybe the time isn't good becauseclutchslipping?

[OED666]

umm.. not sure on that... 127.7MPH doesn't show signs of that..

I personally have done 13.8 @ 99 mph, and later on, a 15.1 @ 98MPH... no slipping clutch, just wheel spin caused the slow time.

Why are people ALWAYS just looking for an excuse... :S

Also, has anyone noticed the silver BA XR6T I posted up pages ago. It seems that one was let go through to the keeper!

Looks like the keepers got this one too...

I've read the whole thread and didn't see a mention on how a clutches rating is determined. I'm interested to know if anyone knows?

Adam - Torque Capacity = Clamp Load x Coef. of Friction x Mean effective radius x No. of Clutch Discs. (I had very briefly covered it, but now its in detail)

There is a calculation on how the clutches should hold the Torque. It is a mathematical equation to work it all out. This is what NPC did many years ago to start the development with Mal Wood Automotive and the clutches. We have worked together using the calculations from the experts in this field, and then road testing in cars. Also feedback from customers from what we have supplied...

Now, lets all remember that some variables are not taken into account.. The clamp actually applied to the disc (if the disc is slipped), tempreature etc.. These are pretty much controlled by the person operating the pedals...

Thanks for the info.

Still don't know what clutch to get.............. :(.....................Fark should of brought a Auto....lol

[STAINLESS again plz]

Mine obviously went to pewp because of semis full time. No more explaing needed.

Funny thing though is I ran a 12.7@119 with no slipping. Although car did only make 2 passes that day.

It actually span through first and second.

I ran it in for around 1000km of daily driving as instructions.

Was installed by Pride Performance in Keysborough.

It slipped with a 3k launch on street fairly early on.

I did talk to mick about it I think on the chat here.

He said some people have a habbit of slipping them a bit off the line. I dunno why I just left it at that, was probs just hoping it would come good and made no further plans for mick to check it out for me.

Since then I honestly hardly drive it and very rarely give it anything, but on occasion when I have it has sometimes given me some nasty smells.

Latest was just recently when headsex took it for a spin, shifting 2nd it just didnt want to grab.

I babied it home from then and its been in my driveway since.

Have been in talks bout fitting a glide so havnt really cared about getting clitch replaced, hence no calls to you.

But honestly, if I do replace the clutch I can not see myself with any malwood clutch.

So unless your gunna give a refund, I dont see the point in me calling.

My purpose here was just answering OP's question, and stating my experience.

Clutch failed with nearly 100kw less than rating.

[Never had any say Panda]

Clutch ratings are SA kw's!!!

It all makes sense now :-P
